Shea Campbell bagged a brace in the victory over Armagh

David Hawthorne gave City an early lead but Dungannon levelled through Rodney McAree's 34th minute penalty.

Campbell's back-post finish gave the home side a 2-1 half-time lead and the striker netted the third on 82 minutes.

Armagh's Mark Gracey was sent-off for a head-butt two minutes later before late goals from Mark McAllister and Shane McCabe completed the rout.
